ORGAN.

SPECIFICATION forming part of Letters Patent N o. 691,501, dated January21, 1902. Applioationrled December 28, 1900. Serial No. 41,430. (Nomodel.)

To @ZZ whom it may concern:

Bo it known that I, CHRISTIAN STOLLE- WERK, music-teacher, a subject ofthe King of Prussia, German Emperor, residing at 49 AlL fonsstrasse,Aix-la-Ohapelle, in the Kingdom of Prussia, Empire of Germany, haveinvented certain new and useful Improvements in Organs; and I. do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My present invention relates to organs, hai'-,

. moniu ms, and other keyed wind instruments,

but principally to a device withthe.. help of which the player can makeresound an y combination of registers at any point of the keyboard,though his hands and feet be employed in the usual manner at play. Thiscircumstance is of great importance, as the player is not compelled 'tolitt his hands o the keys in order to manipulate the organregist-ers,for which operation hitherto a pause was necessary.

In the accompanying drawings, Figure 1 is a vertical section of akeyboard provided with my invention. Fig. 2 is a rear view of theAmechanism directly connected with the registers. Fig. 3 is a view ofthe mechanism in its lowered position. Fig. 4 is a front'view of thekeyboard and part of the workin g mechanism. Fig. 5 is a plan view of atappet.

The parts marked 1 form part of an organhousing and may be of anysuitable'construction. The keyboard 2 and itskeys 3 may likewise be ofany known type.

An important part of 4my invention is the thumb-board 4, pivotallyattached to the organ-housing in posts 5 by means of the rods 6 andextending over the whole length of the keyboard, so as to be within easyreach of the thumbs of the players hands at any point of said keyboard.`Near the turning-point of the thumb-board is attached an arm or arms 7,provided with a slot in the free end surrounding a bolt S, by means ofwhich the thumb-board may beadjusted. Between the organ-housing and saidarm 7 a spring 9 or any other deviceis interposed to return thethumb-board to its original position as soon as the pressure of` thethumb or thumbs has m ovably arranged.

i been removed. Near the upper end of the thumb-board another arm 10 issecured, and pivotally fastened to its free end is the link 11. -Thislink is attached to a slotted lever 12, inovably secured to the base 13,and carries on its under side the bent lever 1,4, held to the link 11 bymeans of the eyebolt 15 and spring16. Against the adjustingscrew 17,with 'a head 18, of leather, rubber, or any other material, in the post19, the lower end of the bent lever 14strikes when the mechanism islowered. y (See Fig. 3.) Opposite to the slotted lever 12 are attachedtwo posts 20, between which the -short slotted lever 21 is In the slot22 of this lever 21 is placed the doublear1nedlever23, having a tooth24, entering lthe teeth ofv the ratchet 25 on the drum 26. Theproportions of the tooth of lever 23 andthe point ofthe lever 14 aresuch Vthat the tooth 24 catchesthe point ofa tooth of the ratchet beforethe point of lever 14 leaves it. A spring 27 keeps the tooth 24 incontact with the ratchet.y -The posts 2O are connected by aplate 28,against which the point of the screw29 bears, passing through an openingin the leaf-spring 30,

tending to press the lever 21 against the plate 2S. In the spurs ofposts 2O is journaled the horizontal part of the le'ver 31, having aforked upper end, surrounding one of the pins 32 of drum 26. The levers31 and 12 are connected by a rod 33, consisting of two parts havingright and left thread, respectively, in orderV to bring the levers 31and 12 closer together or separate them by turning the nut v 34 in onedirection or` the other.

The base 13 is provided with bearings 35, in which the shaft 36 of thedrum 26'revolves. The circumference of said drum is provided with anumber of laths 37, against which,...

rest reversible tappets or keys38, coming into contact with the pins 39and the hooks 40 of the bars `41, hinged to the organ-housing 1.

Flush with the front of the upper part of the organ-housingare suspendeda number of bars 42, united at their lower extremities by a cross-bar43, thus forming independent divisions in which are pivotally arrangedthe oblong boards 44, each provided .with an arm 45. The bars 42 andcross-bar 43 are connected by means of bars 46 with a second IOOcross-bar 47, provided with a screw 4S, for each oblong board 44. In theeye of each screw is fastened one end of either of the two sets ofsprings 49 or 50, and these springs keep the oblong boards in theposition into which they are thrown by the contact of their pin with atappet. The hinged bars 41 are provided with an adjusting-screw 51,likewise provided with a head 52 and so adjusted that when the upper endof the oblong boards 44 strike in their tilted position the cross-bar 53the heads 52 will barely touch them.

The base 13 is mounted upon two or more hinged bars 54, operated'bymeans of the push-button 55, its rod 56, and bell-crank 57, journaled inthe bracket 58, secured to the organ-housing. The rod 56 is providedwith a catch 59, suitable to slip over the pin 60, in which position thebase 13 and all the parts connected therewith are ready for work.v

The tappcts 38 (shown in Fig. 5) are loosely screwed or otherwisemovably fastened into the drum 26, and are provided with a broad and anarrow wing. The narrow wing is of less depth than the broader wing inorder to turn said tappets, notwithstanding the adjacent laths 37,against which the broadfwing rests when struck by a pin 39 or a honk 40.The object in making the wings of different widths is to allow the pin39 to come into con-` tact with the tappet when the broader part isturned one way and to miss it when turned the other way. If, however,the tappet 38 is turned in a direction opposite to that in which itstrikes the pin 39, the hook 40 will be struck by the broader wing ofthe tappet and thepin 39 can pass without beingtonched.'

By'this simple arrangement the period during which a certain register isto remain open can be regnlatedat will. If, for instance, a certainregister has to be kept open for a given time in a combination intendedto be played, the player sets a suitable number of tappets in suchmanner that the broad wings of said tappets will come under the pin 39of the oblong board connected by its rod 61 to the slide of thatparticular register. The first of said series ofl tappets will strikethe pin 39 and tilt its oblong board, (see Fig. 1,) and as thereby thepin 39 gets without the reach of the tappets belonging to the sameseries they cannot influence it any further. The hook 40 being missed bythe narrow wings of the K tappets will remain idle; but ifit isdesirable to close the register the tappet following said series oftappets is set in such a manner that the `hook 40 will be influenced andclose the register by returning the oblong board 44 into its verticalposition by means of the screwhead 52. If it is desirable to keep saidboard in this vertical position, the broader wings of the tappets willbe turned into the path of the hook 40 and it will be moved by eachtappet, but cannot influence the board 44.

The shape of the tappet may be varied at will. The small wing may beomitted in order to economize space where a great number cannot executean undesired motion.

of registers has to be operated, andconsequently a great number ot'tappets must be placed upon the drum.

In operation the thumb-board 4 is pressed inward at the opportunemoment, whereby the point of the bent lever 14 must turn the drum 26. Bymeans of the illustrated connections the fork of the lever 3l must leaveits pin 32, but not before the cross-bar 62 of the lever l2 has forceditself between the pin above it and the next in order that the drlxm nextra security to the same end is aimed at by providing thevlever 23with a tooth 24, so that the drum cannot by chance move forward orbackward when such movement is notdesirable. Whether few or many ofthewoblong boards are to be operated during a certain partial rotationof the drum isdecided lby the combination ot' registers whichthe playerintends to use. In order to arrange such combination before the playcommences, the player lifts the button 55 andthe base 13 and the drumare lowered, whereby the contact between the upper tappets and oblongboards is broken and at the same time the tooth 24 and the point of thebent lever 14 are withdrawn from the ratchet 25, because in descendingthe free end of the double-armed lever 23 strikes the cross-bar 63 andits other arm is forced downward and compels the horizontal arm of thebent lever 14 to descend likewise as the hinged loop 64 does not allowsaid bent lever to remain in its former position when the toothed arm oflever 23 is com polled to descend. The hinged levers 4lare ICO preventedfrom moving too for back by means of the adjusting-screws 65 in thecross-bar 47. If the combination of registers has been set, the tappets38`must retain their position on account of the springs 66 pressingagainst their broad wings, and by pushing back the button 55 all partsare brought into a work- IIO ing position and will respondvto the callofthe player as soon as he touches the thumbboard 4.

Itis evident that the arrangement and shape vof the several parts may bealtered atwill without departing from the spirit of my invention.

Itis a matter of importance to have the drum 26 and the oblong boards 44always in full view during the play and to be able to close, ifnecessary, a register earlier than originally intended bysimply tiltingthe iden tical oblong board back in itsvertical position by the pressureof the hand before its lever 41 can accomplish it. The boards may beprovided with lettersor signs indicating the registers with whichthey'are connected. Likewise the different rows of tappets may benumbered or marked in any desirable manner to aid the player in settingthe tappets for any combination of registers.

I claimp l. In an organ the combination with a keyboard of athumb-board, a drum, links and eli levers for rotating said drum, aratchet and pins for prevent-ing chance motion of said drum, reversibletappets on said drum, means for operating the organ-registers throughcontact with said tappets comprising contactpins on oblong boardspivotally suspended engaging said tappets when turned one Way and hookedlevers engaging them when turned the other way, and a rod and bell-crankto raise and lower the drum and the mechanism connected therewith.
